RENSSELAER HITT, OF \VATERLOO, IOWA, ASSIGNOR OF ONE-HALF TO PETER S. DOELAN, OF SAME PLACE.

WAGONe-JACK.

SPECIFICATION forming part of Letters Patent No. 371,887, dated Qoteber 18, 1887.

' Application filed June 30, 1887.

Serial No. 242,984. (No model.)

To all whom it may concern.-

Be it known that I, RENssELAER Hrrr, a citizen of the United States, residing at Waterloo, in the county of Black Hawk and State of Iowa, haveinvented certain new and useful Improvements in Wagon-Jacks; and I do de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings represents a wagonjack embodying myimprovements. Fig. 2is a plan view of the same.

My invention relates to lifting-jacks designed more particularly for the raising and supporting of the axles of vehicles while lubricating the axles and the removal and replacing of the wheels thereon. The invention is, however, capable of other uses.

My improvement consists in the following construction and combination of parts, which will first be fully described, and the points of novelty thenset forth in the claim.

1 represents a base-plate or bed, which supports the standard 2 and the other parts of the machine. The standard 2 is rigidly bolted to the base, and is provided with a central vertical passage, within which the lifting-bar 3 moves, as will be hereinafter set forth.

4 is a cap on top of liftingbar 3, on which the wagon-axle rests when raised.

5 is a projecting arm at the top of standard 2. It is curved at its inner end, so as to rigidly embrace the standard.

6 is the operating-lever. It is pivoted in the outer end of arm 5 by a pivot, 7, and its inner end is split or bifurcated, so as to clear the arm 5 and the standard 2.

8 is a' vertical slot cut entirely through the standard 2.

9 is a cross-head secured to the lower part of the lifting-bar 3 and projecting through both sides of the slot 8.

10 10 are two links arranged on each side of the standard, the upper ends of which are pivoted at 11 11 in the-bifurcated ends of lever 6.

12 is a hook-latch pivoted to the lever 6,

and adapted to engage the eye or staple l3 when the lifting-bar 3 is raised, and hold it in that position as long as may be desired.

WVhat I claim, and desire to secure by Letters Patent of the United States, is-

In a wagon-jack, the combination of a hollow slotted standard open at the top, a lifting bar working therein, a projecting arm secured to the-top of the standard, a bifurcated lever journaled on said projecting" arni, and two links secured to each prong of said lever and at their lower ends to opposite sides of said lifting-bar, substantially as set forth.

In testimony whereofI affix my signature in presence of two witnesses.
